The electric actuator of the electric valve is driven by AC or DC electricity. According to the action mode, it can be divided into two types: electric switch type and electric external monitoring type. The electric actuator is easy to use energy, has a long signal transmission speed and transmission distance, is convenient for centralized control, has high sensitivity and precision, is easy to cooperate with electrical monitoring instruments, and is simple to install and connect. At the same time, the shortcomings of electric actuators are complex, and the average failure rate is higher than that of pneumatic actuators. It is suitable for places with low explosion-proof requirements and insufficient air.
What is the "regulated condition" of the electric actuator of the electric valve
1. Environmental conditions: environmental characteristics, such as temperature, humidity, air pressure, magnetic field, mechanical shock, vibration, dust, etc.
2. Power conditions: power characteristics.
3. Load condition: refers to the load characteristics that affect the performance of the electric actuator, such as torque, the type and characteristics of the controlled object, etc.
The position transmitter adopts gear transmission to ensure reliable and accurate position limit. The precision conductive plastic potentiometer with angle indication is convenient for debugging. The easy-to-understand circuit adopts epoxy resin encapsulated module structure, high and low temperature aging, to ensure the stability and reliability of the motor, and outdoor servo motor overload protection.
